Hi Constantin. Thank you for looking at my benchmark. > Am 24.07.2015 um 08:57 schrieb Constantin Makshin : > > Well, after looking at the code I can say that the was you wrote this > benchmark "abuses" the QVector's copy-on-write semantic, making it > somewhat biased towards std::vector — you us

Re: [Interest] Qtcontainerbench std::vector vs QVector

Well, after looking at the code I can say that the was you wrote this benchmark "abuses" the QVector's copy-on-write semantic, making it somewhat biased towards std::vector — you use only non-const versions of QVector::begin(), QVector::end() and indexing methods. That leads to a lot of [obviously

"vector" branch is identical to "master". On 07/22/2015 10:20 PM, Gunnar Roth wrote: > Hi, > for whom it may concern i post my results for vector iterating using > iterator and index plus insert via push_back. > > the test code is at https://github.com/gunrot/qtcontainerbench in > branch vector.

[Interest] Qtcontainerbench std::vector vs QVector

Hi, for whom it may concern i post my results for vector iterating using iterator and index plus insert via push_back. the test code is at https://github.com/gunrot/qtcontainerbench in branch vector. it runs over N containers where N=min(1,10/co
